Bis[μ2-bis(diphenylphosphanyl)methane-κ2P:P′]bis(μ4-diphenylphosphinato-κ4O:O:O′:O′)bis(μ2-trifluoroacetato-κ2O:O′)tetrasilver(I) acetonitrile disolvate

Abstract

In the cation of the title compound, [Ag4(C2F3O2)2(C12H10O2P)2(C25H22P2)2]·2CH3CN, the two independent Ag+ cations are four-coordinated in a distorted tetrahedral geometry by one P atom from a bis(diphenylphosphanyl)methane (dppm) ligand, one O atom from a trifluoroacetate anion and two O atoms from two diphenylphosphinate (dpp) ligands. Two dppm ligands, two dpp ligands and two trifluoroacetate anions bridge four metal atoms, forming a centrosymmetric tetranuclear complex. Intramolecular C—H...O hydrogen bonds and a weak π–π interaction [centroid–centroid distance = 3.9804 (13) Å] are also observed.
